–x + y = –3 (a)
3x + 2y = 9 (b)
Lt's eliminate y , by multiplying a) by -2
-2(–x + y) = -2(–3) → +2x - 2y = +6 (c). Now add (c) to (b)
+2x - 2y = +6 (c).
3x + 2y = 9 (b)
----------- --------
5x + 0 = 15 and x = 15/5 and x = 3
To find y, plugin the value of x in any of the equation, sat (a):
–x + y = –3 (a) → -3 + y = -3; y = -3+3 → y = 0
So the solution is (3,0) Answer C

Step-by-step explanation:
alaikum salam.
<u>2. </u><u>find</u><u> </u><u>cos Ф, sin Ф, tan Ф</u>
cos Ф = 5 / 13
Ф = 67.38
sin Ф = 12 / 13
Ф = 67.38
tan Ф = 12 / 5
Ф = 67.38
-----------------------
<u>3. find sin β, cos β, tan β</u>
sin <u>β</u> = 4 / 5
<u>β</u> = 53.13
cos <u>β</u> = 3 / 5
<u>β</u> = 53.13
tan <u>β</u> = 4 / 3
<u>β</u> = 53.13
(2 x 2) + (4 x 4 x 4) x (4 x 4 x 4) =
4 + 64 x 64 =
4 + 4096 =
4100
